IMPROVED APPARATUS FOR HEATING'APARTMENTS BY HOT WATER.

Specification forming' part of Letters Patent No. 30,065, datedSeptember 18, i860.

Be it known that we, JACOB F. HUNTER and.

F. W. GEIssENHAINER, both of the city .of New York, in the county land.State of New York, have invented a 'new and Improved Hot-VVater Stove;and we do hereby declare that the following is a full andexact'description thereof.

The nature of our invention consists in aA novel arrangement andcombination of parts constituting a new portable hot-water stove.

It also consists in the employment ofya deiiecting-cone in theinteriorof such stove, as

Awill be explained below.

To enable others skilled in the art to make and use our invention, wewill proceed to describe it by the aid of the drawing, which is l across-section 'through the apparatus.`

lM is a gas-burner of any suitable character constructed with a' view todeveloping heat ratherthan light by the combustion of the gas, and vn isa pipe conducting the gas thereto from the main. (Not represented.)

G is a conical coil of metal pipe, cc1nn1uni-- eating at thevbase withthe pipe J and at the top with the pipe J H is`a similar, but larger,coil, surrounding G and supported at a little distance therefrom. Itcommunicates at the bottom and top withl the pipes I and J, which extendhorizontally in the opposite direction from 'those with which G isconnected. The coils of the pipes G and H are not in close contact., butstand at a suiiicient distance each from the 'other to allow of thepassage between each convolution and the next'of a small quantity 'otflame or heated air.

A is a conical case surrounding the double coils'Gand` Hat a sufficientdistance therefrom-'to lallow affre'e circulationiot the products ofcombustion. Itis'openat the base and communicates at its topI with apipe, B, leading to the chimney of' the building. K is a deiiectorafVhollow double cone of metal 'mounted within the interior coil,-G. It isof such. diameter 'as nearly to vfill the space therein. Y

C C aresections of a circular tube which extends around A andreceive'the pipes .I J. D D represent similar sections ofa'correspondingcircular tube located at a lower level andcommunicatingwith the pipes .I I.

P-P are vertical pipes connecting C witliD.

The exteriors of P as also of C and D are'exposed to the atmosphere ofthe apartment,

which circulates freely among and about their y heated surfaces.

The hot products of combustion rising from the burner M are defiectedoutward by the cone K and circulate through all the spaces. By thismea-ns the-heated air is conveyed into the space between theconical coilG andthe l corresponding larger coil,'H, and fr'orn this space itescapes in a similar manner through i the spaces betweenthe'convolutions of H and iills the interior of the case A, but at amuch reduced temperature, in consequence of `the i airhaving parted witha large portion of its heat in its contact with the cool coils GH. I tultimately rises and escapes from the case A, through the pipe B, intothe flue or chimney. The coils Gand H, asr alsothe pipes I,'C, P, D,

vessel opening into (I to ll up the apparatus heat applied to coils Gand Ilcauses the water in them to rise, as indicated by the blue an dthence downward through pipes P Pinto l), returning back to coils G andH through pipes I J at base at areduced temperature, to

radiation from C, P', andD is taken up bythe air in the apartment, whichby this means beheat-receiving and the heat-diffusing water- With adividing partition in any manner equivalent to ours.

and J are filled with water. E represents a and to allow for expansionof water. The

arrows, and flow through pipes I and J into C,

be again heated, as before'. The heat lost by comes heatedthrough vtheprimary agency of parts combined and arranged inconnectionl Our stovevmaybe used for coal, Wood.;` or other fuel, if desired, in lieu of gas,the severalvpipesbeinga11-i1ed with Water, and the effec-1 5 will be todiuse the heat'l in the sameV manner as above indicated. p

Having now-fully described our invention, what We claim as new` therein,anddesire to secure by Letters Batent, is-

1. The combination and arrangement of the coi1's` of pipe G and II, ortheir equivalent Waff` ter-heatingsurfaqe, the casing A; and one o1"vmore annular butradiating vessels, or one or incre series of air-heatingpipes, P, surround.-

ing the same, forming a portable hot-water' stove substantially of thecharacter above set forth.

2. The employment of the coneK in the above-described hotwater stove,arranged relatively to the other parts of the same, substantially 'inthe manner and for the purpose herein set forth v JACOB F. HUNTER.
